We claim the ornamental design for a patterned material, as shown and described.
FIG. 1 is a front view of a patterned material, showing our new design;
FIG. 2 is a front view of the patterned material shown in a first position of use on a jacket drawn in broken lines;
FIG. 3 is a front view of the patterned material shown in a second position of use on a hat drawn in broken lines; and,
FIG. 4 is a front view of the patterned material shown in a third position of use on a glove drawn in broken lines and with the cuff folded outward.
The broken line square perimeter surrounding FIG. 1 and within FIGS. 2-4 depicts the boundaries of the claim and forms no part thereof. All other broken lines depict environmental subject matter that forms no part of the claimed design.
